Yesterday I was baffled how close the neo geo port of shinobi was to the original (compared on mister). It made me wonder why SEGA didn't support the neo geo even with their backcatalog (Shinobi is 1987). It seems that it would have been easy for them to port system 16 to neo geo and would have improved on the whole Neo Geo library. Both companies would have made money out of it....that's for sure.
At the time we would have dreamed of these games as neo geo users...
Even today I'm of the opinion, that the neo geo library consists of mostly mediocre titles.
